前郭灌区退水对查干湖水质的影响

摘要

对比前郭灌区退水进入查干湖多年后的水质主要污染物浓度及富营养化程度变化趋势、 排水干渠至查干湖各区间水质状况、 主要水化学环境因素变化情况、 周边没有引入前郭灌区退水湖泡的水质现状, 认为前郭灌区经排水干渠入湖的退水并未对查干湖水质和富营养化状态造成不利影响, 相反有利于水质改善.%This paper compared the main pollutant concentrations and contrast eutrophication trend of water quality in Lake Chagan,the drainage canal to Chagan Lake water quality of each section,the main factors of water chemistry changes in the environment ,the surrounding not introduced Qianguo Irrigation water recession Lake water Quality Status years later after Qianguo Irrigation area water recession into Lake Chagan;The con-clusion is Qianguo irrigated drainage canal back water into the lake does not adversely affect water quality and eutrophication in Lake Chagan state,on the contrary in favor of improving the water quality.
